IMPROVEMENT IN RECUMBENT CHAIRS.

Specification forming part of Letters Patent No. 174,627, dated March14, 1876; application filed June 1 5,1s75.

To all whom it may concern Be it known that I, WILLIAM HEATH, of Bath,of the county of Sagadahoc and State of Maine, have invented a new anduseful Improvementin Recumbent Chairs and do hereby declare the same tobe fully described in the following specification, and represented inthe accompanying drawings, of which- Figure l is a top view, Figs. 2 and3 opposite side elevations, Fig. 4 an under-side view, and Fig. 5 alongitudinal section, of a chair provided with my invention.

In this chair the back A and the seat B are to be or are hingedtogether, and the seat is provided with a leg-rest, L, which should alsobe hinged to the seat and have arms a a extending up from it and jointedto the chair-arms O 0, such chair-arms at their rear ends being jointedto the back A. The seat, at or near the middle of each end, I pivot tothe supportframe 1), the pivots being shown at b b, and I provide suchseat-frame with a deep tie or board, 0, extending across itlongitudinally near its middle, as shown. Against one side of the board0 I arrange a friction-arm, E, pivoted at its outer end to the leg-rest,such arm being connected with the board 0 by a pendulous connection-bar,d, pivoted to the frictionarm and to the board 0. To operate with thefriction-bar there is a friction-toggle, F, which, arranged as shown, ishinged to the frontbar 6 of the frame D, and is connected to a lever, H,by a bar, G, which is pivoted to both toggle and lever. The said levergoes through the part c, and is fulcrumed thereto and jointed to anotherlever, I, arranged in the frame D in manner as shown. A spring, K, fixedat one end to the board 0, bears against the longer arm of the lever H.

From the above it will be seen that not only or otherwise, by means ofthe friction-arm and toggle, the spring serving to keep the toggleforced up to the friction-arm, and the system of levers enabling asitter to move the toggle back, so as to enable the friction-arm toreadily move with the leg-rest.

By having the seat pivoted at its ends to the frame it will operate tobetter advantage than if rigidly fixed thereto; but it may be rigidlyfixed to the frame, the chair being in other respects as described.

I claim-- 1. In a recumbent chair having attached to its seat B amovable back, A, and a leg-rest, L, connected by arms 0 O a a, asdescribed, a friction-arm, E, applied to the legrest and support-frameB, as set forth, in combination with a clamp or toggle, F, applied tosaid support-frame and friction-arm, and' provided not only with aspring, K, to force it toward the friction-arm, but with levers H I fordrawing it away therefrom, all substantially as described.

2. The seat, pivoted, at or near the middle
